AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND JUNCTION CO 255 PM MDT THU JUL 3 2008 .SHORT TERM...TONIGHT THROUGH SATURDAY... HIGH PRESSURE COVERS UTAH AND COLORADO AND THIS WILL CONTINUE THROUGH INDEPENDENCE DAY. TERRAIN AND DIURNALLY DRIVEN ISOLATED STORMS HAVE DEVELOPED THIS AFTERNOON AND EXPECT SIMILAR CONDITIONS FOR THE HOLIDAY. WATER VAPOR REVEALS THE AIR MASS IS DRIER OVER THE NORTHWEST HALF OF THE FORECAST AREA...THE MAIN REASON THAT CONVECTIVE ACTIVITY HAS BEEN SLOWER TO DEVELOP OVER THE NRN MOUNTAINS. ONE SUBTLE CHANGE FOR FRIDAY...PRECIPITABLE WATER IN THE MODEL DATA RISES A NOTCH OVER THE FOUR CORNERS. THE SOURCE OF THE MOISTURE INCREASE COMING FROM THUNDERSTORM OUTFLOWS FROM NORTH CENTRAL NEW MEXICO THIS AFTERNOON. THUNDERSTORM COVERAGE MAY INCREASE A NOTCH FRIDAY AFTERNOON/EVENING FOR THE SRN ZONES...BUT MOS POP GUIDANCE DOES NOT SHOW MUCH OF AN INCREASE. INCREASED THE COVERAGE OF SLIGHT CHANCE POPS...BUT DID NOT RAISE ANY VALUES INTO THE CHANCE CATEGORY. WITH THE WARMEST 700 MB TEMPS SO FAR...INDEPENDENCE DAY MAY BE THE HOTTEST DAY SO FAR THIS SUMMER. RIDGE WEAKENS ON SATURDAY AS PACIFIC NORTHWEST SHORT WAVE SKIRTS ACROSS THE NRN TIER STATES. THE TAIL END OF THIS WAVE MOVES ACROSS WRN COLORADO DURING THE PEAK HEATING HOURS. AS MENTIONED IN THE PREVIOUS PARAGRAPH...PRECIPITABLE WATER WILL HAVE INCREASED AHEAD OF THIS SHORT WAVE. WATER VAPOR SHOWS BORIS GETTING ENTRAINED INTO THE SOUTHWEST FLOW AHEAD OF THIS SHORT WAVE...NOT SURE IF MODELS HAVE PICKED UP ON THIS MOISTURE PLUME THAT IS EVIDENT IN THE WATER VAPOR. BUT THE GFS AND WRF HAVE INCREASED CONVECTIVE PCPN...ESPECIALLY THE SAN JUAN MOUNTAINS...FOR SATURDAY AFTERNOON. SO HAVE INCREASED POPS OVER THE SRN AND CENTRAL MOUNTAINS WITH CHANCE POPS WHERE MOISTURE WILL BE MORE READILY AVAILABLE AS COMPARED TO THE NRN MOUNTAINS. WITH INCREASED CLOUD COVER...AFTERNOON TEMPERATURES WILL BE A LITTLE COOLER THAN THE FOURTH OF JULY. .LONG TERM...SATURDAY NIGHT THROUGH THURSDAY... SATURDAY NIGHT THROUGH MONDAY...STILL LOOKS LIKE WESTERLY FLOW TO THE NORTH OF OUR CWA DURING THIS PERIOD IN RESPONSE TO A COUPLE OF SHORTWAVE PACIFIC TROUGHS THAT WILL SUPPRESS THE UPPER HIGH INTO AZ AND NM. THIS SHOULD BE A DRIER PATTERN FOR OUR CWA...AND NOT QUITE AS WARM AS WE ARE CURRENTLY EXPERIENCING. STILL MAY HAVE ISOLATED DIURNALLY-DRIVEN THUNDERSTORMS OVER THE MOUNTAINS OF OUR CWA SUNDAY AND MONDAY...THOUGH EXPECT BY MONDAY THAT THEY WILL BE CONFINED TO WESTERN SAN JUAN MOUNTAINS. TUESDAY THROUGH THURSDAY...RESURGENCE OF STRONG UPPER RIDGE EXPECTED OVER THE AREA WITH UPPER HIGH CENTER MIGRATING NORTHWARD. WE SHOULD SEE TEMPERATURES 5-10F ABOVE NORMAL AGAIN...GENERALLY AROUND 100F EACH DAY IN THE CLIMATOLOGICALLY WARMER AREAS OF OUR CWA WITH SOME OF THE HOTTEST LOCATIONS IN SE UT REACHING THE 105F MARK. THERE ARE INDICATIONS FOR A LITTLE INCREASE IN CONVECTIVE CLOUD DEVELOPMENT BY WEDNESDAY OR THURSDAY. BUT STILL LOOKS TO BE GENERALLY DRY WITH ONLY HIGH-BASED THUNDERSTORMS. && .AVIATION...ISOLATED THUNDERSTORMS WILL CONTINUE INTO EARLY EVENING...WITH MOST STORMS DISSIPATING BY 04Z. A FEW STORMS WILL DRIFT OVER THE LOWER VALLEYS. EXPECT LOCAL MVFR VIS AND CIGS NEAR SOME STORMS...MAINLY OVER THE MOUNTAINS. GUSTY THUNDERSTORM OUTFLOW WINDS EXPECTED IN THE LOWER VALLEYS. OTHERWISE...VFR CONDITIONS TO PREVAIL THROUGH TONIGHT. EXPECT SIMILAR CONDITIONS ON JULY 4TH. && .HYDROLOGY... MOUNTAIN SNOWPACK CONTINUES TO DWINDLE AND RUNOFF WILL GRADUALLY DECREASE RESULTING IN A SLOW LOWERING OF RIVER AND STREAM FLOWS THROUGH THE WEEK. ALTHOUGH WATER LEVELS ARE DECREASING FLOWS REMAIN COLD...SWIFT...AND TURBULENT. CAUTION IS URGED WHEN AROUND RIVERS AND STREAMS. && .GJT WATCHES/WARNINGS/ADVISORIES... .CO...NONE. .UT...NONE. SHORT TERM.....PF LONG TERM......JRP AVIATION.......TAL HYDROLOGY......TGJT
